If your dock has a lane running somewhere between 550 and 1,500 miles, the math on that lane has quietly changed this year. Truckload spot rates were sitting close to 29 percent above last year’s levels through most of July, and intermodal has not moved anywhere near that fast. On the exact lanes where rail and truck compete head to head, the gap between them has widened enough that shippers who never looked twice at intermodal are pricing it out now.
This is not a story about intermodal getting cheaper. It is a story about truckload getting more expensive faster, on the specific distance band where rail can compete.
Why 550 to 1,500 miles is the lane where this plays out
Intermodal has always had a structural advantage on long hauls, rail moves freight at roughly a third of the fuel cost per ton-mile compared to a truck, and that gap only grows with distance. Under 550 miles, the two drayage legs on either end of an intermodal move eat too much of that savings for rail to compete. Above 1,500 miles, intermodal usually wins outright because the linehaul efficiency overwhelms everything else.
The 550-to-1,500-mile band sits in between, and it has historically been the toss-up zone, the range where truckload’s speed and simplicity were often worth paying a little extra for. That premium is what has changed. Truckload’s price is climbing on a schedule intermodal is not following, so the toss-up zone is tipping toward rail on more lanes than it was a year ago.
What is driving the spread
Two separate things are pushing this spread wider, and they are not the same problem. Diesel climbed for three straight weeks through late July and sat close to 40 percent above last year’s level by the end of the month, and that fuel cost lands directly on a truckload rate. Intermodal carries a fuel surcharge too, but a smaller one, since less of the total move runs on diesel-burning equipment.
Underneath the fuel spike sits a separate, slower-moving story. Truckload capacity has been contracting for months, fewer active trucks chasing a similar amount of freight, and that scarcity has been pushing rates up independent of what diesel does week to week. Intermodal capacity does not face the same pressure. Rail networks and container availability move on longer cycles than the driver and equipment market does, so intermodal has stayed comparatively stable while truckload has been reacting to both fuel and capacity at once.
Van tender rejections, a measure of how often carriers turn down loads they are contracted to haul, have been running well above where they sat over the past several years. When rejections climb, shippers get bumped to the spot market more often, and the spot market is exactly where this year’s rate pressure shows up hardest.
What converts and what should stay on the road
Not every lane in that mileage band is a candidate, and treating intermodal as a blanket swap is how shippers end up disappointed. The freight that converts well shares a few traits. It can tolerate an extra day or two of transit time. It is not chasing a tight delivery appointment. It has consistent volume on a lane close enough to a rail terminal that drayage does not eat the savings.
Industrial equipment moving on a set restocking schedule, CPG freight with forgiving delivery windows, and construction materials staged for a project timeline rather than a specific hour all tend to be strong fits. A rush order that has to land at a dock by a fixed time tomorrow morning is not. Matching the mode to what the shipment needs, rather than defaulting to whichever one you have always used, is the entire skill here.
What this means for the two kinds of shipper
Evaluating intermodal usually means a separate conversation with a rail-focused provider, a different quoting process, and enough friction that a lot of small shippers never get around to it even when the savings would be real. If a lane fits the profile above, that conversation is worth having this quarter, while the spread between the two modes is wider than it has been in years.
GoShip’s lane is the other side of that decision. For everything that does not qualify for intermodal, the rush orders, the tight appointment windows, the lanes without the volume to plan drayage around, the freight is staying on the truck no matter what the rate spread looks like. That is exactly the freight where a tight market punishes shippers who wait on a callback. On a self-service platform, you pull live rates from vetted carriers yourself, compare them, and book, instead of routing a rush quote through a broker and hoping it comes back before the capacity is gone.
Three questions before you make the call
You do not need a freight science degree to make this call. You need honest answers to three questions.
First, does the shipment have flexibility on delivery time, even a day or two of slack. Second, is the lane distance in the range where rail’s linehaul efficiency has room to work, generally 550 miles and up. Third, does your volume on that lane run consistently enough that you can plan drayage instead of scrambling for it shipment by shipment.
If the answer to all three is yes, it is worth pricing that lane with a rail-capable provider this quarter, while the spread is this wide. If the answer is no on any of them, the freight is staying on the truck, and that is where you want the fastest, most competitive rate you can get. You can price that lane right now and see where the truckload market has your shipment sitting today.
